Huh? What are you storing? Why does it need to be portable… Why does it have to be small? Your wanting to store couple TB, why would you be using device sized 256GB devices if you need couple TB?

If you gave some details of what exactly your doing - it would be easier for people to suggest a way to accomplish it…

If I wanted smallest form factor to store 2TB of data, I would just get a 2TB ssd… I think buffalo puts out a pretty small one, for around 100 bucks… I think its smaller than 1x0.5x3 inches, And believe its suppose to be some sort of mil standard impact certified or something… One sec, let me look up a link.

here you go https://www.buffalotech.com/products/ssd-put-rugged-and-portable-solid-state-drive-stick

Or you can just get a case for any nvme ssd and use that…

If you own your own domain, no-ip wouldn’t be where I would go no…

I doubt that 9/month price is intended for “home” users… 50 hosts, this seems more suited for a smb that doesn’t really have some senior network engineer setting everything up for them… And more the guy got promoted to IT because hey he knew how to setup the wifi router ;)

For some smb, with a few locations and wanting to have some fqdn point to their changing IP because since well they only have consumer level connections, etc. And they don’t understand how any of it works anyway… 100$ year seems a fairly reasonable price.

$9.0/ month for dynamic dns.

That is the pro version that is up to 50 different hosts, etc.

The “home” user version that you don’t have to validate every 30 days is 1.99 a month… And they still have a free version as well. You just need to confirm it every 30 days.

850 seems a bit low for gig… And you don’t need 6 for gig, shoot you don’t need 6 for over gig…

First test is to nas 1gig interface from my pc, 2nd is to its 2.5ge usb interface… Over cat 5e

Lots of things could come into play on why your not seeing 940ish, etc… Security software on either end of your test. Driver, or driver settings, etc… Some other sort of limiting on either of devices related to load, etc…

But normally yes you should be able to see 900ish for sure on a gig connection everything is running optimally.

If your 40ge is a different network, ie 10.x vs 192.168.x.x and it has not gateway set and you access via the 10.x network IP/fqdn that resolves to the 10.x address you should have no problems.

I access my nas via 2.5ge network between my pc and nas that is on a different network and I see no issues with slow access to the nas for smb.
